I moved your thread description to the first post and trimmed it above, OP, since it was taking up a lot of space on the forum listing. Try to keep thread descriptions under 7 lines so you don't visually crowd out other people's threads. Also, please don't put sandbox links in the thread description; that messes up the forum display on some mobile devices. ~Zyn

I think you have a good opportunity for an interview, maybe with the police officer?
Do the police forces that help patrol know about the girl's anomalous property/know about the girl in general?
Some more clinical sounding terms might be a good thing here, like with "strange disappearance of each criminal."
There are also some words that need to be changed, precede being one of them. Proofreading this might be a good idea. You definitely want some more punctuation.
The thing about not entering the light? Probably want that in the Special Containment Procedures.
This could make a pretty good tale, I think. From the gang or the officer's perspective? Possibly?

Just some thoughts I had, I don't know how valid they are. Feel free to ignore some of them if you feel it's cramping your style/they're just complete idiocy.

Massive fences are erected around a certain block of abandoned houses where SCP-XXX had been found. In truth the fences provides no help in containment since SCP-XXXX does not move outside of a ten foot radius of its area, but instead the fences are meant to keep anyone from venturing into the entity's path.

This is not very good tone.

A more typical way of saying this would be something along the lines of "The block in which SCP-X is known to manifest has been fenced off." Maybe something about deterring trespassers.

SCP-XXXX, also known as the Street Light Girl is described as a pale juvenile female looking to be around the age of ten years old.

You don't really need to include "also known as the Street Light Girl"

"looking to be around " - "who appears to be approximately"

The neighborhood that was said to be the residence of SCP-XXXX is located in Detroit, Michigan that is which completely abandoned.

This goes a bit word salady at the end. I'd suggest "The abandoned neighborhood which is thought to have been the residence of SCP-XXXX is located in Detroit, Michigan"

Seven malevolent entities will then appear around the child's dead body and will precede to harm anyone within their sight. The fence and cameras that surround the containment area will be destroyed as apart of this process and will need to be repaired the following day under daylight. These seven entities that have appeared were seen to have been much taller than the average human and are labeled as SCP-XXXX 1-7. SCP-XXXX 1-7 maintains a humanoid shape cloaked in shadows, but with no visible extremities. Only a long torso that reaches the ground with a featureless head is the best way to describe the seven beings. These seven entities that have been unleashed will continue to rampage for an unknown amount of time as no cameras were left in tact to observe their actions. However it is confirmed that malevolent creatures disappear after nighttime has passed.

You really need to break this paragraph up and clean it up for tone.

Seven malevolent entities will then appear around the child's dead body and will precede to harm anyone within their sight.

I'd remove "malevolent" If they're attacking people indiscriminately we can assume they're not very nice.
I would move the description of the entities and their rampaging to directly after this sentence for coherence.

These seven entities that have appeared were seen to have been much taller than the average human and are labeled as SCP-XXXX 1-7. SCP-XXXX 1-7 maintains a humanoid shape cloaked in shadows, but with no visible extremities. Only a long torso that reaches the ground with a featureless head is the best way to describe the seven beings.

I would put this more briefly - something along the lines of "These entities, designated SCP-X-1 to SCP-X-7, are humanoids, taller than the average human, and have no visible extremities or facial features. Their torsos appear to reach the ground."

These seven entities that have been unleashed will continue to rampage for an unknown amount of time as no cameras were left in tact to observe their actions. However it is confirmed that malevolent creatures disappear after nighttime has passed.

I would suggest something more like "It is unknown how long SCP-X-1 to -7 continue to remain active and/or violent as all cameras are destroyed when they become violent. They have never been sighted after sunrise."

The fence and cameras that surround the containment area will be destroyed as apart of this process and will need to be repaired the following day under daylight.

I'd suggest moving this sentence to the containment procedures and phrasing it more like "After SCP-X-1 through -7 become active, the fences and cameras surrounding the contaiment area will be destroyed and should be repaired during daylight the next day."

Despite the harm that comes to the girl after 2:24 am, she will appear again at the same time only to repeat her cycle of abduction.

This sentence is very much non-clinical tone. "SCP-X will continue to manifest at 2:24am despite having been apparently harmed" would be a little better.
